RAB SUMO-R-12 – Frequently Asked Questions

1) Which part number do I order for the RAB SUMO-R if I need 0-10V dimming?
The dimming versions of the RAB SUMO-R carry a /D10 suffix: SUMO-R-12/D10, SUMO-R-15/D10, and SUMO-R-19/D10. Order the plain SUMO-R-12, SUMO-R-15, or SUMO-R-19 if the fixture is switched only. Dimming is a build option, not a field add-on, so pick it at the order form if the space has occupancy sensors or a 0-10V control layer.
2) What wattages does the RAB SUMO-R round LED high bay come in?
Three wattages: 22W (SUMO-R-12), 26W (SUMO-R-15), and 30W (SUMO-R-19). Each of the three is offered with or without 0-10V dimming, which gives six orderable combinations in total. For a facility standardizing on one fixture across a building, the wattage step lets you match output to mounting height without changing fixture type or trim.
3) Is the SUMO-R a good fit for a warehouse or gym ceiling?
Those are the intended spaces. RAB lists the SUMO-R for warehouses and distribution centers, manufacturing plants, retail and big box, gyms and recreation centers, aircraft hangars, automotive service bays, and industrial workshops. It is a round high bay with a white finish, so it reads clean against painted or open-deck commercial ceilings.
4) Will the SUMO-R flicker enough to bother people working under it all day?
Flicker on the SUMO-R is rated at 30% or less, and it runs on a constant current driver, which holds output steady over the life of the fixture rather than letting it drift as the LEDs age. That combination is what matters in spaces with long shifts or machinery, where visible flicker causes eye strain and stroboscopic effects.
5) How long before I have to relamp the RAB SUMO-R high bay?
You don't relamp it. The SUMO-R is an integrated LED fixture rated for 50,000 hours, so there is no lamp or ballast to service. At around 10 hours a day that is roughly a 13-year run, which is why it gets specified in spaces where getting a lift under the ceiling is disruptive, like hangars and active warehouse aisles.
6) Can I mix dimming and non-dimming SUMO-R fixtures on the same job?
You can, but keep them on separate circuits or zones. The non-dimming SUMO-R-12, SUMO-R-15, and SUMO-R-19 have no 0-10V control leads, so they will sit at full output on a dimmed circuit while the /D10 units track the control signal. If a whole area is going on sensors or a control panel, spec the /D10 version throughout that zone.
7) How wide is the SUMO-R fixture body?
2.95 inches across. That is a compact round profile for a high bay, which is what makes it workable where a large-diameter reflector-style bay would crowd ductwork, sprinkler lines, or a tight joist bay.
